All

Just back from the dealership. Spoke to the technician. He stated that he sick of having to treat this problem, when in fact it's not a problem.
Apparently there are two parameters lumped into the "Ambient conditions" criteria, that are not mentioned in the owners handbook, and that the technicians only got to find out about from Peugeot, when this became a major problem for the dealers.

One we all suspected is the 12v battery system (both main and auxiliary) having to be above a certain charge level. the tech. mentioned 70%, not sure.
The second one, is a temperature sensor within the air conditioning system, which is also a set point (value not known)

I am at least satisfied that the car is running within its design conditions. All we have to do is maintain the 12v batteries charge levels.
It would have been nice to be aware of this before purchase, but at least I can live with it.

Where is the auxilliary 12v battery? The main battery under the bonnet is new and always fully charged.

The auxiliary 12V battery is in the boot section under the floor panel. According to the Peugeot technician, it can also be charged in place, if necessary, with a charger unit.

Hi All Interested Parties

Got the car back today - so far so good. I have to thank the dedication and interest of the head of sales at our local agent who drove our car for almost a month in an effort to root out the problem. Had it been left to the service department we would have just been fobbed off with more ridiculous stories combined with utter contempt. The fact that we asked for our money and our old car back may have helped but credit still due to the salesman. To cut a long story short there are two 12 volt batteries in the system both of which need to be maintained at a high level of charge. Long runs apparently may not be enough to keep the 12 volt system up to scratch if there is any deficiency in the master battery under the bonnet. One way around the problem is to use a trickle charger to maintain the charge level if the car is not in constant use. Luckily our car is under warranty and the battery will be replaced as soon as they can get one (hen's teeth apparently). In the meantime I'll be investing in a trickle charger. Been driving a brand new Hybrid4 purposely keeping it in Electric mode for the last three weeks - engine only started once to clean the Particulate Filter then switched back to Electric - I suspect Peugeot may have quietly solved the Ambient problem on their latest products.
Any recommendations for a good trickle charger with auto cut-off and power display?

Thanks Stansboy1.

Had a look today for the auxilliary battery because I have a sneaking feeling that it may be the culprit. I can't see any way to get at it without a major removal of upholstery.

Has anyone founf a way to get at this battery?
